Yes. Vendors submit applications online and upload required documents — certificates of insurance, health permits, licenses — into a single review queue where organizers can approve, reject, or request corrections, and vendors can ask questions on the document itself. Terms and conditions can be accepted inside the application, and separate contracts can be signed with built-in ESIGN-compliant eSignature. Payments, including add-ons like electricity or equipment rental, are collected in the same flow.
